THE KISS

You have allergy to someone else's saliva except your soulmate. That means you cannot share you food and beverages with anyone except your soulmate. The problem is you don't know your soulmate.

Imagine begins

She was in the college. Sitting on one of the benches of the court after playing badminton. Her bestfriend came and sat beside her. He was holding two bottles of strawberry milkshake. He gave her one bottle. He took a sip and she also took a sip. They kept it on the bench.

"How about a race? Let's see who is faster." He said and held his bottle.

"Let's do it." She said. He called his friend and told him to count till three.

"Hana::Dul::Set" He announced.

Both drank as fast as they could but he won the match. She was late by few milliseconds.

"Shit." They both said at the same time.

"You won. So why shit?" She asked.

"You drank from my bottle."

"Fuck." She cursed and covered her face but there were no rashes on her.

"Wait, you don't have any rashes." He said and removed her hands.

"You know what that means." His friend said and they realised.

He kissed her with all the love he had for her. Both the tongues fight and tasting the strawberry milk they drank a few minutes ago.

As they pulled, a string of saliva still connected them without leaving a rash.
